♥ Outputted revolution in line 5.
② Absolute data content
ⓐ Serial data : This indicates where the motor axis is positioned after several revolutions
from the reference position (Absolute encoder initialized value).
ⓑ Initial incremental indication : It outputs the pulse in the same speed as the revolution
as about 1250 rpm (17 bit serial encoder application and P01-14=16384(4096[pulse])
from the origin position to current motor position of the motor axis.
